Trichaleurina is a fleshy mushroom with goblet-shaped within Pezizales. Many genera have a morphology similar to Trichaleurina, such as Bulgaria and Galiella. Some previous reports had been described fungi like Trichaleurina as Sarcosoma. Indonesia has been reported that has Trichaleurina specimen (the new name of Sarcosoma) by Boedijn. This research aimed to obtain, characterize, and determine the Trichaleurina around IPB University. Field exploration for fungal samples was used in the Landscape Arboretum of IPB University. Ascomata of Trichaleurina were collected, observed, and preserved using FAA. The specimen was deposited into Herbarium Bogoriense with collection code BO 24420. The molecular phylogenetic tree using RAxML was used to identify the species of the specimen. Morphological data were used to support the species name of the specimen. Specimen BO 24420 was identified as Tricahleurina javanica with 81% bootstrap value. Molecular identification was supported by the morphological data, such as the two oil globules and the size of mature ascospores.

Lentinus is a unique genus within Polyporales, because of the lamellate basidiocarp. In Indonesia, Lentinus is commonly for a study about their potential, rarely for their taxonomy. BO 24427 specimen was found in West Java, Indonesia, sited in Landscape Arboretum of IPB University. The specimen was identified using molecular study and supported by some morphological data of fresh fruiting body. molecular identification used ITS region. The phylogenetic tree was constructed using MEGA Version X software. The morphology was based on macroscopic and microscopic observation. The result of molecular analyses showed that BO 24427 specimen was identified as Lentinus squarrosulus with 99% bootstrap value and classified into section Rigidi. The morphological data of fresh fruiting body supported the molecular identification. The important morphological data that classified into Lentinus squarrosulus were scabrous cap and size of basidiospores. This study was the first record for publish the finding of Lentinus squarrosulus in Indonesia.

A New Species

The genus Linum consists of 15 species in Iran. A new species as well as a new record from Iran is described and illustrated here as L. khorassanicum and L. turcomanicum, respectively. The original description of the latter species is incomplete and ambiguous, probably due to incomplete taxon sampling. In this work, after a comprehensive taxon sampling from the entire distribution range of the species in northeast of Iran, the taxonomic description of L. turcomanicum is completed. The present study considers morphological and molecular (the nrITS region) analyses of the both species. In phylogenetic analysis based on the molecular data, we included these species and some related Linum species to examine the phylogenetic relationship of the new species and L. turcomanicum with other members of the genus. Linum turcomanicum is morphologically almost similar to L. austriacum and L. perenne, but it can be distinguished from them on the basis of several traits such as fruiting-pedicel form and length of petal. Likewise, results obtained from the molecular phylogenetic tree are consistent with those obtained from the morphological data. Linum khorassanicum is well characterized morphologically by having erect fruiting pedicels and inflorescence with few flowers. Our results suggest that the morphological data are in agreement with the molecular phylogenetic tree in which the taxonomic status of L. khorassanicum is confirmed as a new species. Based on IUCN Red List categories and criteria, L. khorassanicum and L. turcomanicum are evaluated as Endangered and Near Threatened species, respectively.

The systematic position of three Apiaceae-Apioideae taxa, Pinacantha porandica, Ladyginia bucharica and Peucedanum mogoltavicum, from Middle Asia and Afghanistan, is clarified based on nrITS DNA sequence data. In the molecular phylogenetic tree, the monotypic Pinacantha is placed in unresolved position within the Ferulinae. Although there is no morphological information on essential characters, we propose a new position of Pinacantha porandica within the genus Ferula. As a result a new combination Ferula porandica is proposed, with a new section Pinacantha to accommodate it. The attribution of Peucedanum mogoltavicum to Ferula has been confirmed, its correct name being Ferula lithophila. The genus Ladyginia should not be included in Ferula, its closest relatives being Mozaffariania and Glaucosciadium from the Glaucosciadium Clade.

Drosophila lini and its two sibling species, D. ohnishii and D. ogumai, are hardly distinguishable from one another in morphology. These species are more or less reproductively isolated. The mitochondrial ND2 and COI-COII and the nuclear ITS1-ITS2 regions were sequenced to seek for the possibility of DNA barcoding and to reconstruct the phylogeny of them. The character-based approach for DNA barcoding detected some diagnostic nucleotides only for monophyletic D. ogumai, but no informative sites for the other two very closely species, D. lini and D. ohnishii, of which strains intermingled in the molecular phylogenetic trees. Thus, this study provides another case of limited applicability of DNA barcoding in species delineation, as in other cases of related Drosophila species. The molecular phylogenetic tree inferred from the concatenated sequences strongly supported the monophyly of the cluster of the three species, that is, the lini clade. We propose some hypotheses of evolutionary events in this clade.

Abstract— The genus Eleocharis (Cyperaceae, monocotyledons) is characterized by bladeless leaves, which are leaves having only leaf-sheaths. To study the evolutionary process through which Eleocharis species lost their leaf blades, we analyzed the outer morphological and anatomical characters of the representative Eleocharis species, plus species from nine phylogenetically related genera. From the analysis, we recognized eight characters and we optimized their character states on a recent molecular phylogenetic tree. As a result, we recognized five characteristics shared by Eleocharis species as follows: (1) the most apical internode is more than seven times longer than the next apical internode; (2) bladeless leaves having only leaf sheaths; (3) transversely septate aerenchyma in culms; (4) densely and peripherally located, slender, and square timber-shaped fiber bundles in culms; and (5) palisade chlorenchyma in culms. In these characteristics, (2) and (4) are synapomorphies of Eleocharis. These two apomorphic characteristics seemed to be adaptations for inhabiting running waters.

Phylogenetic Lineages

The morphologically variable moss Trichostomum brachydontium is very common in south and west Europe, particularly under Mediterranean and Atlantic climates. A morphological study was conducted alongside a molecular phylogenetic study based on nr ITS and cp rbcL regions in order to assess if T. brachydontium is an exceptionally polymorphic species as evidenced by the number of described infraspecific taxa from the last century or, alternatively, if it includes more than one species, and if so, to find the valid name for them. Phylogenetic analyses of both nuclear and chloroplast datasets show that there are four well-supported clades. While the ITS based tree is in good agreement with the morphological data, there are a few inconsistencies with reference to the rbcL tree; this may be explained by incomplete lineage sorting or by hybridization. The morphological survey revealed well-defined discriminate differences between the four phylogenetic lineages. The taxonomic conclusions include the recognition of four species: T. brachydontium s.s., T. herzogii (a new name proposed for var. cuspidatum), T. littorale and T. meridionale (a new name proposed for var. densum). Lectotypes are designated for T. brachydontium and T. littorale. Our results underline the ongoing need of integrative studies to examine further the underestimated diversity of the T. brachydontium complex in other regions.

Males And Females

A Ruehmaphelenchus species was isolated from an ambrosia beetle, Euwallacea fornicates, during a biodiversity survey of entomophilic nematodes in Taichung, Taiwan. The new species is characterised by a unique tail morphology in both males and females, and a unique spicule morphology in males. The male spicule has clear dorsal and ventral limbs (connected by a blade-like cuticle), a triangular membrane-like structure on its sides, and short, conspicuous, laterally oriented, projections at the distal end. In a molecular phylogenetic tree, inferred from near-full-length small subunit (SSU: 18S) and D2/D3 expansion segments of the large subunit (LSU: 28S) of ribosomal RNA, the new species and other nominal and undescribed Ruehmaphelenchus species formed a well supported clade within Bursaphelenchus. Although this result supports a previous study that suggested that Ruehmaphelenchus is a junior synonym of Bursaphelenchus, the generic relationship between Ruehmaphelenchus and Bursaphelenchus remains somewhat uncertain. Therefore, R. formosanus n. sp. is described as a member of Ruehmaphelenchus, although this should be regarded as a tentative placement.
